Datatypes

Python Data Types

Variables can hold values, and every value has a data-type. Python is a dynamically typed language; hence we do not need to define the type of the variable while declaring it. The interpreter implicitly binds the value with its type.

a = 5

The variable a holds integer value five and we did not define its type. Python interpreter will automatically interpret variables a as an integer type.

Python enables us to check the type of the variable used in the program. Python provides us the type() function, which returns the type of the variable passed.

Consider the following example to define the values of different data types and checking its type.

// Some code
a=10  
b="Hi Python"  
c = 10.5  
print(type(a))  
print(type(b))  
print(type(c))  

Python has the following data types built-in by default, in these categories:

Text Type:	str
Numeric Types:	int, float, complex
Sequence Types:	list, tuple, range
Mapping Type:	dict
Set Types:	set, frozenset
Boolean Type:	bool
Binary Types:	bytes, bytearray, memoryview

Getting the Data Type

You can get the data type of any object by using the type() function:

Example

Print the data type of the variable x:

x = 5
print(type(x))

Setting the Specific Data Type

If you want to specify the data type, you can use the following constructor functions:

Setting the Specific Data Type

If you want to specify the data type, you can use the following constructor functions:

Example	Data Type		Try it
x = str("Hello World")	str
x = int(20)	int
x = float(20.5)	float
x = complex(1j)	complex
x = list(("apple", "banana", "cherry"))	list
x = tuple(("apple", "banana", "cherry"))	tuple
x = range(6)	range
x = dict(name="John", age=36)	dict
x = set(("apple", "banana", "cherry"))	set
x = frozenset(("apple", "banana", "cherry"))	frozense
x = bool(5)	bool
x = bytes(5)	bytes
x = bytearray(5)	bytearray
x = memoryview(bytes(5))	memoryview
